基于python連接oracle導(dǎo)并出數(shù)據(jù)文件
python連接oracle,感覺table_list文件內(nèi)的表名,來卸載數(shù)據(jù)文件
主腳本:
import os
import logging
import sys
import configparser
import subprocess
import cx_Oracle
#判斷輸入?yún)?shù)個(gè)數(shù)
class param():
def check_para(self):
if len(sys.argv) != 1:
print("請輸入正確的參數(shù):yyyymmdd")
exit(1)
else:
print("繼續(xù)執(zhí)行")
#根據(jù)配置文件獲取登錄信息
class get_dbini():
def get_db(self):
config=configparser.ConfigParser()
filepath="db.ini"
if os.path.exists(filepath):
config.read_file(open(filepath))
dbinfo=[config.get("db_oracle","username"),\
config.get("db_oracle","password"),\
config.get("db_oracle","ip"),\
config.get("db_oracle","dbsid")]
else:
loginfo.info("沒有那個(gè)配置文件")
sys.exit(4)
#聲明使用全局變量
global username,password,ip,dbsid
username=dbinfo[0]
password=dbinfo[1]
ip=dbinfo[2]
dbsid=dbinfo[3]
loginfo.info(username+password+ip+dbsid)
#導(dǎo)出表數(shù)據(jù)
class exp_date():
def exp_table(self):
with open('table_list','r') as f:
list = f.readlines()
for i in list:
tablename = i.rstrip('\n')
exportquery='sqluldr2 user='+username+'/'+password+'@'+ip+':1521/'+dbsid+' query="select * from '+tablename+';" head=no file='+tablename+'.dat field=0x03 record=0x030x0a safe=yes'
loginfo.info("開始導(dǎo)出數(shù)據(jù): exportquery= "+exportquery)
flag= subprocess.check_call(exportquery,shell=True)
loginfo.info(flag)
#打印日志
class log_set():
def logger_set(self):
logger=logging.getLogger('mylogger')
logger.setLevel(logging.DEBUG)
fh=logging.FileHandler('a.log','w')
fh.setLevel(logging.INFO)
ch=logging.StreamHandler()
ch.setLevel(logging.ERROR)
formatter = logging.Formatter('%(asctime)s -%(name)s -%(levelname)s - %(message)s')
fh.setFormatter(formatter)
ch.setFormatter(formatter)
logger.addHandler(fh)
logger.addHandler(ch)
return logger
if __name__=='__main__':
loginfo=log_set().logger_set()
param().check_para()
get_dbini().get_db()
exp_date().exp_table()
DB配置文件內(nèi)容:
db.ini
[db_oracle]
username=c##scott
password=tiger
ip=192.168.1.250
dbsid=orcl
表名字的配置文件:
table_list
BONUS
DEPT
EMP
LEAD_TABLE
SALGRADE
T1
TB_USER
TEST
XGJ
XGJ_2
運(yùn)行結(jié)果:
[oracle@master2 tmp]$ python3 c.py
繼續(xù)執(zhí)行
